Assessment of the Validity and Internal Consistency of a Performance Evaluation Tool Based on the Japanese Version of the Modified Barthel Index for Elderly People Living at Home

Abstract

[Purpose] This study aimed to examine the validity and internal consistency of the Japanese version of a performance evaluation tool for activities of daily living (ADL) based on the modified Barthel Index (PET-MBI) among elderly people at home. [Subjects] The subjects were elderly people living at home in Japan. [Methods] A cross-sectional study was performed at five home care facilities for elderly people in Japan. ADL performance was evaluated for 128 participants using the PET-MBI, which included 10 self-care items. We used confirmatory factor analysis to estimate the factorial validity. We assessed data model fitness with the χ2 statistic, the Goodness of Fit Index (GFI), Adjusted Goodness of Fit Index (AGFI), and Root Mean Square Error of Approximation (RMSEA). Cronbach’s alpha coefficient was used to determine the internal consistency. [Results] The mean age of the participants was 79.1±8.9 years. Among the 126 participants included in the analysis, 67 were women (53.2%). The single-factor model demonstrated a fair fit to the data, with the χ2 statistic = 74.9 (df =35), GFI = 0.88, AGFI = 0.81, and RMSEA = 0.096, and the path coefficients of each item ranged from 0.44 to 0.95. The alpha coefficient of the 10-item scale was 0.93. [Conclusion] The PET-MBI for elderly people at home was well validated.

Development of the Dementia Assessment Sheet for Community‐based Integrated Care System 8‐items, a short version of the Dementia Assessment Sheet for Community‐based Integrated Care System 21‐items, for the assessment of cognitive and daily functions

“…The MMSE, Lawton IADL scale and Barthel Index are well verified and widely used in Japan. [16][17][18][19] In the current study, a strong correlation was observed between the DASC-21 and the MMSE, Lawton IADL scale and Barthel Index. Therefore, the DASC-21 has sufficient concurrent validity to assess both cognitive functions and ADL.…”

Is the Barthel Index an Adequate Assessment Tool for Identifying a Risk Group in Elderly People Living at Home?

“…This gives an essential role to people's subjective judgement and assessment of their own living situation since there is a correlation between functional decline and subjective quality of life [2]. One important component of quality of life for elderly people, in particular, is the ability to perform activities of daily living independently [7].…”

Dysphagia in Multiple System Atrophy of Cerebellar and Parkinsonian Types

“…Patients with other neurologic disorders, neuropsychological dysfunctions, and/or head and neck cancers, and those undergoing tube feeding were excluded. We checked the disease duration and assessed the activities of daily living of each patient on the Japanese version of the modified Barthel Index [7]. The modified Barthel Index is commonly used to assess patient's capacity to perform 10 daily tasks without assistance and the patients were scored with a sum of 100.…”

“…The modified Barthel Index is commonly used to assess patient's capacity to perform 10 daily tasks without assistance and the patients were scored with a sum of 100. The Japanese version of the modified Barthel Index demonstrated satisfactory factorial validity and internal consistency in elderly people living at home [7]. The ethics committees of Fukuoka University Hospital and National Omuta Hospital approved the study, and an informed consent was obtained from all participants.…”
